Japanese researchers authored a study in the Journal of American Ophthalmology showing reduced-fluence photodynamic monotherapy for polypoidal choroidal vasculopathy patients improved and maintained visual acuity over two years.
The study reported the results of a two-year follow-up study of PDT treatments in 38 eyes of 38 PCV patients. Researchers measured visual acuity and optical coherence tomography every 3 months post-PDT procedure, and used angiography tests to evaluate vascular lesions.
Results showed the treatments were effective at improving visual acuity through one year, and maintained the positive results at two years. The average number of treatments was 1.9, which the authors note is fewer than intravitreal injection of anti-vascular endothelial growth agents.
